on earth did wild man dennis rodman become the first american to meet the secretive dictator of north korea? >>> and lover's leap. she's afraid to jump. he nudges her off a cliff. talk about a breakup? the story behind the daredevil dive. >> i'm breaking up with you! >>> good evening. tonight, we begin in rome. for the first time in 600 years, the seat of st. peter is vacant because a living pope has returned to his quiet life. taking off the red shoes and the papal robes. benedict xvi also took off that papal ring that you see on his finger. and tonight, it has been scratched with an "x" across the face so no one else can ever use his papal seal. and then, he turned and walked back into his new life, his academic life, with his books, his piano, his beloved cat awaiting him, as the bells tolled to mark his final day. and they are the same bells that filled the air on his first day as pope eight years ago. so, now it is time for the great debate about a new pope and a new day for the ancient church.
